远程属性不允许发布

Question

我试图检查TerminalID是否已被其他型号占用。 Ajax正确回发并且也可以看到错误消息，但页面不允许我提交，我只需要在输入时检查此信息以显示错误消息然后发布。请帮帮我

型号：

public class MoveModel
{
    [Required]
    [Remote("CheckExistTrm", "MoveModel")]
    public int TerminalID { get; set; }

    public string User { get; set; }
    ........
}

控制器：

public JsonResult CheckExistTrm(int TerminalID)
    {
        var terminal = db.Terminals.Find(TerminalID);
        if (terminal == null)
            return null;
        var agrdet = (from t in db.AgreementDetails where (t.TerminalID == terminal.TerminalID && t.Condition == "New") select t).FirstOrDefault();
        if (agrdet != null)
        {
            var agreement = db.Agreements.Find(agrdet.AgreementID);
            return Json("consider! this terminal is active in the agreement: " + agreement.AgreementNumber ,JsonRequestBehavior.AllowGet);     
        }
        else
        {
            return Json(true, JsonRequestBehavior.AllowGet);
        }

    }

查看（我正在使用devexpress）：
